See Stephen King, James Franco in First '11/22/63' Set Photo

Casting was still underway earlier this week for Hulu's upcoming adaptation of Stephen King's "11/22/63," but production has already kicked off on the miniseries.

King posted the first photo from the set a few days ago, posing with star James Franco, who plays lead Jake Epping, alongside J.J. Abrams, who's producing the show under his Bad Robot banner. "11/22/63" centers around high school teacher Epping traveling back in time to try to prevent President John F. Kennedy's assassination on the titular date.

"Everything looks cool," King wrote on Twitter alongside the photo, and we're excited by the author's assessment. When a follower inquired when the series would debut -- there's no firm release date yet -- King said that was to be determined, but that fans should prepare to be entertained.
